Overview

14V / 28V, replaces Ford, Electrodelta, Prestolite, Interav, Wico, FVR, and more voltage regulators. (Refer to Model Eligibility for your more information and additional models)

The Plane Power R1224 Voltage Regulator is a solid-state voltage regulator with over-voltage protection, field short (over current) protection, and reverse battery protection. The Plane Power R1224 Voltage Regulator also supports precision load sharing for twin applications, and an alternator inoperative lamp.

NOTE: The R1224 voltage regulator is designed to be setup in the field for 14 or 28 volt operation by configuring the two jumpers within the voltage regulator.

Attention:
Some applications require accessory part number 07-03532. See Application Guide for requirements.

So far it is working well. Mechanic installed just yesterday and I flew it back from Dallas to Houston. I should have made this change when I had the planepower alternator installed. Both work great together.

As advertised! The terminal block requires new ends on the conductors as they were smaller than OEM and the screws are very small. I installed this on a Lake LA4-200 along with a Planepower alternator. It’s working nominally.

Replaced the 50+ year old regulator and associated noise filter assembly in a PA28-140 with this regulator. Fairly easy to install with minor mounting changes, works as advertised.

Have Lyc-320 engine overhauled my A&P Has replaced several of the factory alternators with the plane power alternator and regulator and said they worked out great I’ll be another month before mines done

Used to replace my old InterAv regulator. Was more work than just replacing the regulator (some re-wiring) but works great.

I had been chasing alternator problems, it would come online then off again. My C172 (1965 F) had standard Cessna voltage reg and Electrodelta over voltage sensor. Narrowed it down to faulty Over voltage sensor. Cost to replace about same as plane power R1224-14v. Easy decision for me. Get rid of separate device and upgrade newer technology to all in one. Tech support was extremely knowledgeable on pre-purchase questions. Install was a breeze. Everything changed out and adjusted in less than 30 minutes, and no more alternator problems problems. I even got back my over/under voltage warning indicator that someone had disconnected who knows when? Even if it goes out in 3-5 years as some say, $190 bucks is a cheep throwaway, and I’ll be glad to get a new one.

Easy to hook up and works right out of the box , replaced a Over Votage relay and regulater at the same time that is no longer avalible , saves room for being small in size

Quality part, much better than original STC unit. Adjustable voltage, set at lowest voltage from factory, had to adjust to get proper voltage. Excellent paperwork included.

Voltage regulator worked great once it was wired correctly. We followed the instructions for our plane, making sure that we followed them correctly. Problem is that the instructions were wrong. Tech Support was very helpful in telling us the right wiring diagram.

Screws are pretty small for an old guy working under the panel upside down. I should have relocated it to the firewall like most of them are.

Replaced the old InterAv regulator and over voltage relay in my Piper Comanche in one unit. Not hard if you follow the instructions carefully. Works just fine. I like that it is easy to adjust the bus voltage to the value recommended by the battery manufacturer for your operating temperature.,14.25 for my Concorde battery. Glad to replace the 40 year old technology with something better. Be prepared to replace the old wire terminations with new - they are a weak spot.

They are indeed throw away, I just did but as I worked thru the issues I ended up sending mine back to Hartzel/PP where they bench tested it and pronounced it failed. So they threw it away and after 6 years I bought a new one. Please note, keep your existing ground wire, it is not included in the package. I sent mine back w/ the unit and we had to fabricate a new one.

We installed a R1224 on our 14V Skylane three years ago. At the time, Plane Power provided service for them. Hartzell Engine Technologies / Kelly Aerospace / Plane-Power now states that they are disposable - if they break just throw it away. Mine failed after 3 years
